LinkQuest is the dominant supplier of underwater acoustic modems in the world. Its SoundLink High Speed
Acoustic Modems transport more than 95% of the world's acoustic communication
data. These
systems have set a series of technical performance records in field deployments
all over the world. The SoundLink acoustic modems have formed the world's largest underwater acoustic
communication networks with hundreds of nodes.

LinkQuest's line of TrackLink
Acoustic Tracking Systems
provide the world's most robust, accurate and cost-effective Ultra Short
Baseline (USBL) solutions. The TrackLink
systems are the world's best selling USBL tracking systems.

FlowQuest Acoustic Current Profilers
are ideal for measuring currents
and flows in oceans, harbors, lakes and rivers. With its capability for
significantly longer range, standard deepwater depth rating and seamless
integration with third-party sensors and LinkQuest acoustic modems, the
FlowQuest system is not just a current profiler but also serves as a focal point
for underwater deployments.

NavQuest Doppler Velocity Logs (DVL)
are ideal for precision
navigation and positioning of underwater vehicles. With their capability for
fast and accurate velocity output, significantly longer range and smaller
minimum altitude comparing against similar products, the NavQuest Doppler
Velocity Logs are the excellent choices for underwater precision navigation
applications.

EchoSweep 300 Multibeam Echosounder is a high-resolution, highly robust and cost-effective swath bathymetric system for mapping of
sea floor, inland waterways and reservoirs. The EchoSweep system is a useful tool for hydrographic and
bathymetric surveys, underwater inspections, dredging, pipeline inspection, cable-laying, and many other
underwater applications.

LinkQuest's Precision Marine Geodetic
System
is the world's only commercial acoustic positioning system capable of better
than 0.5 cm in accuracy. These systems have been extensively deployed for
Tsunami and earthquake monitoring and prediction.
